@section MySQL full-text search
Since version 3.23.23, @strong{MySQL} has support for full-text indexing
and searching. Full-text index in @strong{MySQL} is a special type of index
called @strong{collection}. Collections can be created from @code{VARCHAR},
@code{TEXT}, and @code{BLOB} columns at @code{CREATE TABLE}
time or added later with @code{ALTER TABLE} or @code{CREATE COLLECTION}.
Collection is queried with @code{MATCH} function.
@example
mysql> CREATE TABLE t (a VARCHAR(200), b TEXT, COLLECTION (a,b));
Query OK, 0 rows affected (0.00 sec)
mysql> INSERT INTO t VALUES
-> ('MySQL has now support', 'for full-text search'),
-> ('Full-text indexes', 'are called collections'),
-> ('Only MyISAM tables','support collections'),
-> ('Function MATCH ... AGAINST()','is used to do a search'),
-> ('Full-text search in MySQL', 'implements vector space model');
Query OK, 5 rows affected (0.00 sec)
Records: 5 Duplicates: 0 Warnings: 0
mysql> SELECT * FROM t WHERE MATCH (a,b) AGAINST ('MySQL');
+---------------------------+-------------------------------+
| a | b |
+---------------------------+-------------------------------+
| MySQL has now support | for full-text search |
| Full-text search in MySQL | implements vector-space-model |
+---------------------------+-------------------------------+
2 rows in set (0.00 sec)
mysql> SELECT *,MATCH a,b AGAINST ('collections support') as x FROM t;
+------------------------------+-------------------------------+--------+
| a | b | x |
+------------------------------+-------------------------------+--------+
| MySQL has now support | for full-text search | 0.3834 |
| Full-text indexes | are called collections | 0.3834 |
| Only MyISAM tables | support collections | 0.7668 |
| Function MATCH ... AGAINST() | is used to do a search | 0 |
| Full-text search in MySQL | implements vector space model | 0 |
+------------------------------+-------------------------------+--------+
5 rows in set (0.00 sec)
@end example
Function @code{MATCH} matches a natural language query @code{AGAINST} a
text collection. For every row in a table it returns relevance -
similarity measure between the text in that row (in the columns, that
are part of the collection) and the query. When it used in a @code{WHERE}
clause (see example above) the rows returned are automatically sorted
with relevance decreasing. Relevance is a non-negative floating point
number. Zero relevance means no similarity. Relevance is computed based
on number of words in the row and number of unique words in that row,
total number of words in the collection, number of documents (rows),
that contain a particular word, etc.
MySQL uses very simple parser to split text into words. "Word" is
any sequence of letters, numbers, @code{'}, and @code{_}. Any "word"
that is present in stopword list or just too short (3 characters or less)
is ignored.
Every correct word in the collection and in the query is weighted,
according to their significance in the query or collection. This way, a
word that is present in many documents will have lower weight (and may
even have a zero weight), because it has lower semantic value in this
particular collection. Otherwise, if the word is rare, it will receive a
higher weight. Weights of the words are then combined to compute the
relevance.
Such a technique works best with big collections (in fact, it was
carefully tuned up this way). For very small tables word distribution
does not reflect adequately their semantical value, and this model
may sometimes produce bizarre results.
